I've heard, but haven't been able to verify, that RHEL comes with proprietary management tools that aren't available in CentOS. Do you know about that?

Just to make matter worse, under Ubuntu, XDM config is beneath /etc/X11,

I neglected to mention, on all of the distros I cited, the "/etc/X11" directory is still there. It's just that the "gdm" and "kdm" sub-directories have been moved to their own separate directories.

Well, I've verified that "gdm" and "X11" locations are the same for all the current versions of Debian, Ubuntu, and CentOS. (I haven't verified that for "kdm", since my Feisty Fawn Kubuntu is the only KDE distro that I'm currently running.) So, if the exam were to just cover the RHEL/Debian/Ubuntu world, you'd probably be safe with asking about specific locations.

On the other hand, if the exam is to be truly "distro-agnostic", then you might still have a good point, since I don't know if other distros are using other locations for the "gdm" and "kdm" directories. (But then, the exam isn't truly "distro-agnostic" now, since the only package systems it covers are the Red Hat and Debian/Ubuntu package systems.)

The most high-profile example I've heard of is the San Francisco Chronicle. Last year, they decided to upgrade from the Red Hat 6 that they were running, but couldn't afford the support contract for RHEL. So, they switched to CentOS, instead.

My client has had me do several OpenVZ projects with CentOS. It works like a champ, once you get it figured out.

I haven't played with Fedora in ages, so Bryan can probably advise you better on that.

The three light-weights I've played with lately are Xubuntu, and the XFCE versions of Vector Linux and Sidux. Of the three, I've found that I like Sidux the best.

Ciao,
